Default Help with Lake City Production Dates

Hopefully somebody has this info readily at hand. I've spent hours searching the interwebs. Please forgive me if it's right in front of me on these forums. Hopefully nobody will suggest I look at the head stamp as these cans remain sealed for now.
These are the large tall o.d. sealed spam cans marked as follows:

520 Cartridges
Cal .30 Ball M2
In Cartons
Lot LC 39182

I've also got lots 39189 and lot 39220
I found an internet post that stated LC lot #39182 was mfg in 1952 but I don't trust the source. I would like to confirm production dates as well as confirmation these lot numbers are non corrosive.
Any help is greatly appreciated.
Stay safe!

From what I've found is that LC lot#13700 was the first non-corrosive M2 from June 1951.
Based on your lot's, what you have is way beyond the starting lot. Can't help with dates.

The last WW2 lot of .30 caliber ball was #13699. Lake City closed in August 1945, then was re-activated for Korea in early 1951, starting with lot #13700, shown on the chart above as the first batch of non-corrosive. Production of .30 caliber M2 ball continued at Lake City until 1975, when it was finally terminated.

Lot numbers for the 1950s, under which your three fall, started at #13700 in 1951 and ended at #39802 in 1959. The changeover from the 13000 series lot numbers to the 39000 series occurred when the lot number 13999 was reached. Continuing on sequentially to 14000 did not occur as the 14000-15999 block of lot numbers had been assigned to Denver. Only true way to determine production date is to check headstamp, but based on the lot number breakdown in my 1959 copy of TB 9-AMM 4 (Small Arms Ammunition Lots and Grades), your lots probably fall within the 1953-1955 timeframe, and are all non-corrosive,

Hope this helps. Charlie

Charlie, it helped out a lot. Pretty much confirms what I had found earlier but really didnít trust the source. Found one of the lots was 1954 and that agrees with your findings. I canít remember which lot specifically but the lot #ís are so close together the date range you stated is good enough, as well as confirmation itís all non corrosive. Many thanks for your post!

My pleasure. I just wish the Ordnance bulletins from the 50s contained a more detailed lot number/year breakdown like the WW2 versions.
